University of Dayton Campuswide Energy Efficiency
Size 1,753,900 SF
HEAPY investigated energy-saving opportunities for the University of Dayton utilizing the AES Ohio, formerly DP&L, Retro-Commissioning Incentive Program for the Science Center and Fitz Hall. Because of the success of these first two buildings, UD then opted to do an additional 14 academic buildings. This Retro-Commissioning study focused on identifying opportunities for optimization of existing systems relative to energy efficiency, without compromising appropriate operational conditions in the facilities. As part of this study, HEAPY investigated the following primary building systems along with the associated ancillary systems and controls:
Operational improvements to the Hot Water and Chilled Water Plants and related pumping systems. Typical investigation strategies are but are not limited to:
- CW Supply Pump Differential Pressure Reset
- Chilled Water Supply Temperature Reset
- Chiller Plant Enable and Staging Strategies
- HW Pump Differential Pressure Reset
- Heat Pump Loop Differential Pressure Reset
- Heat Pump Loop Water Temperature Reset
Operational improvements to Air Handling and Exhaust Systems. Typical investigation strategies are but are not limited to:
- Air Handling Unit and Zone Level operational scheduling
- Heating and Cooling Temperature Set point optimization
- Supply Air Temperature Reset
- Supply Airflow Static Pressure Reset
- Economizer Sequence Validation and Optimization
- Dedicated Outdoor Air Ventilation Unit Optimization
- Demand Controlled Ventilation
